The long time is pretty much always due to a slow file system (it takes about 3 minutes with my laptop using the local disk) but on a desktop machine using a network file system it can take up to 20 minutes. We generally always build on a local disk; since disk space is so cheap now pretty much any machine has gigabytes free of disk space that you can use to build on.
I think two hours is totally unacceptably long. What type of system are you building on and where is the file system? My guess is /home/reddy is off on some slow filesystem away from the machine you are compiling on.
